MALTA, Deborah Carvalho et al. The COVID-19 Pandemic and changes in adult Brazilian lifestyles: a cross-sectional study, 2020. Epidemiol. Serv. Saúde [online]. 2020, vol.29, n.4, e2020407.  Epub Sep 21, 2020. ISSN 1679-4974.


To describe lifestyle changes with regard to consumption of tobacco and alcohol, food intake and physical activity, in the period of social restriction resulting from the COVID-19 pandemic.


This is a cross-sectional study conducted in Brazil with data from the ConVid online health behavior survey. The data were collected via an online questionnaire answered by the survey participants. Post-stratification procedures were used to calculate prevalence rates and 95% confidence intervals.


45,161 individuals aged 18 years or more participated. During the period of social restriction participants reported a decrease in practicing physical activity and an increase in time spent using computers or tablets or watching TV, intake of ultra-processed foods, number of cigarettes smoked and alcoholic beverage consumption. Differences were observed according to sex and age group.


The results indicate a worsening of lifestyles and an increase in health risk behaviors.
